Objectives: To compare real-world, long-term outcomes of laser and anti-vascular endothelial growth factor (VEGF) therapies in patients with retinopathy of prematurity (ROP).
Methods: This was a multicentre retrospective study. We included 264 eyes of 139 patients treated for type 1 ROP or aggressive ROP (AROP) who were followed for at least 4 years. Laser treatment was initially performed in 187 eyes (the laser group), and anti-VEGF therapy was initially performed in 77 eyes (the anti-VEGF group). We collected data on sex, birth characteristics, zone, stage, and the presence of plus disease at the time of treatment and best-corrected visual acuity (BCVA), spherical equivalent (SE), and ocular complications (amblyopia and strabismus) in patients aged 4-6 years. We investigated the associations between treatment outcomes (BCVA, SE and the presence of amblyopia and strabismus) and influencing factors, including treatment procedure (anti-VEGF or laser therapy), sex, birth characteristics, zone, stage, and the presence of plus disease, using multivariable analysis and logistic regression analyses.
Results: The initial treatment procedure was not associated with any specific treatment outcome. Subgroup analysis of patients with zone I ROP revealed that the anti-VEGF-treated eyes had significantly better BCVA and higher SE than laser-treated eyes (p = 0.004, p = 0.009, respectively). Female patients presented significantly better BCVA, less amblyopia and less strabismus than male patients (p < 0.001, p = 0.029, p = 0.008, respectively).
Conclusions: In zone I ROP, anti-VEGF therapy led to better visual acuity and less myopic refractive error than laser treatment.
